Specification of Letters Patent.

Application filed November 27, 1908. Serial No. 464,571.

To all whom it may concern.'

Be it known that I, JOHN C. RICK, a citizen of the United States of America, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lead-Pipe Couplings, of which the follow@ ing is a specification, reference being had therein to the accompanying drawing.

This invention relates to a lead pipe coupling, and the object of my invention is the provision of simple and eifective means, for establishing' a non-leakable connection between a lead pipe and a wrought iron pipe.

I attain the above object by providino a coupling constructed along the lines of a union, an intermediate connecting member of a novel form being used to provide a continuous passage from a lead pipe to a wrought iron pipe or similar conduit.

The detail construction entering into the invention will be hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal sectional view of the coupling, and Fig. 2 is a cross sectional view of the same.

.Referring to the drawings in detail, 1 designates a soft metal pipe having one end flared as at 5 and fitted upon the said pipe 1 is a coupling member 2 formed at one end with an exteriorly threaded collar 3 irovided with a cavity or concave recess L1 1n the face thereof and in the recess 4L projects the flared end of the pipe 1, the length of the flared end of the pipe 1 in longi tudinal section being lessthan the depth of the recess 4.

The reference character 8 denotes a coupling memberformcd at one end with a collar 9 provided with a cavity or recess 10. The

'diameter of'the collar 9 is less than the diameter of the collar 3 and the recess of the collar 9 opposes the recess of the collar 3. The member 8 at one end is formed with interior threads 11 whereby a pipe-branch can be connectedl to the said member 8..

The diameter of the recess 'f1 in the collar 3 is the same as that of the recess 10 in the 4coupling member being will conform to the shape of the recess in the coupling members. The member 6 eX- tends within the recess of the coupling member and engages the flared ends 5 of the pipe 1.

To connect the coupling members 2 and 8 together and to cause a snug engagement of the connecting member 6 with the wall of the recess 10 and the Vflaring end 5 of the pipe 1, a flanged sleeve or nut 12 is employed. The sleeve 12 has its inner face for a portion of its length provided with screw-threads which engage with the threads l can be interposed between the member 6 and the collar 9. The reduced diameter of the collar with respect to the diameter of the collar 3 allows for clearance when positioning the sleeve 12 upon the coupling members.

Ha ving now described my invention, what l claim as new,;--

In combination, a coupling member coinprising a tubular section and an integral collar, said collar being formed with an inner recess adapted to be engaged by a connecting member ova] shaped in crosssection, the outer face of said collar being formed cylindrical and provided with a right-angular shoulder, a second coupling member of like construction, said secon ternal screw-threads, a anged soft metal pipe in the second coupling member with the flanged end thereof located in therecessed collar of said second coupling member,

said recess being so formed that the collar is provided with a sharp edge engaging the soft metal pipe, a member formed oval in cross-section having a bore of less diameter than the. bores of the coupling members located between the recessed collars thereof, said .member vbeing adapted to force the flanged end of the soft metal pipe a 'ainst the adjacel'lt collar, and aflange nut rovided with eX-' mounted on the first collar with the ilange thereof engaging the right-angular shoulder coupling-members fixed midway of the transthereof, the inner peripheralvedge of said verse thickness of the oval-shaped member. 10
